ICD-10-CM Code G02

Meningitis in other infectious and parasitic diseases classified elsewhere

Version 2021 Billable Code Manifestation Diagnoses

Valid for Submission

G02 is a billable code used to specify a medical diagnosis of meningitis in other infectious and parasitic diseases classified elsewhere. The code is valid for the fiscal year 2021 for the submission of HIPAA-covered transactions. The ICD-10-CM code G02 might also be used to specify conditions or terms like african trypanosomiasis, candidal meningitis, central nervous system candidiasis, coccidioidal meningitis, coccidioides infection of the central nervous system, cryptococcal meningitis, etc

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code G02:

Code First

Code First
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
  • underlying disease, such as:
  • African trypanosomiasis B56
  • poliovirus infection A80

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
  • candidal meningitis B37.5
  • coccidioidomycosis meningitis B38.4
  • cryptococcal meningitis B45.1
  • herpesviral herpes simplex meningitis B00.3
  • infectious mononucleosis complicated by meningitis B27
  • measles complicated by meningitis B05.1
  • meningoencephalitis and meningomyelitis in other infectious and parasitic diseases classified elsewhere G05
  • mumps meningitis B26.1
  • rubella meningitis B06.02
  • varicella chickenpox meningitis B01.0
  • zoster meningitis B02.1

Code Edits

The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10 Code Edits are applicable to this code:

  • Manifestation diagnoses - Manifestation codes describe the manifestation of an underlying disease, not the disease itself, and therefore should not be used as a principal diagnosis.


The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • African trypanosomiasis
  • Candidal meningitis
  • Central nervous system candidiasis
  • Coccidioidal meningitis
  • Coccidioides infection of the central nervous system
  • Cryptococcal meningitis
  • Cryptococcus infection of the central nervous system
  • Cysticercosis of central nervous system
  • Enterovirus meningitis
  • Fungal meningitis
  • Histoplasma infection of central nervous system
  • Meningitis caused by Histoplasma capsulatum
  • Meningitis caused by Histoplasma duboisii
  • Meningitis caused by Histoplasmosis
  • Meningitis caused by Human poliovirus
  • Meningitis caused by Mucorales
  • Meningitis caused by Taenia solium
  • Meningitis caused by Trypanosoma brucei
  • Parasitic meningitis
  • Trypanosoma brucei gambiense meningitis
  • Trypanosoma brucei rhodesiense meningitis
  • Trypanosomiasis with meningitis

  • 321.1 - Mening in oth fungal dis (Approximate Flag)
  • 321.2 - Mening in oth viral dis (Approximate Flag)

Information for Patients


Also called: Spinal meningitis

Meningitis is inflammation of the thin tissue that surrounds the brain and spinal cord, called the meninges. There are several types of meningitis. The most common is viral meningitis. You get it when a virus enters the body through the nose or mouth and travels to the brain. Bacterial meningitis is rare, but can be deadly. It usually starts with bacteria that cause a cold-like infection. It can cause stroke, hearing loss, and brain damage. It can also harm other organs. Pneumococcal infections and meningococcal infections are the most common causes of bacterial meningitis.

Anyone can get meningitis, but it is more common in people with weak immune systems. Meningitis can get serious very quickly. You should get medical care right away if you have

  • A sudden high fever
  • A severe headache
  • A stiff neck
  • Nausea or vomiting

Early treatment can help prevent serious problems, including death. Tests to diagnose meningitis include blood tests, imaging tests, and a spinal tap to test cerebrospinal fluid. Antibiotics can treat bacterial meningitis. Antiviral medicines may help some types of viral meningitis. Other medicines can help treat symptoms.

There are vaccines to prevent some of the bacterial infections that cause meningitis.
